FILLING comrounn sofa 'rnnn-onvirins. I

No it) rawingi Bait known that I, JAMEsQF. Trains I "won'rn, a citizen oftheUnited States, residing-at'flthaca, in the county of Tompkins and State of New York, have invented new and useful Improvements in Filling,

Compounds for Tree-Cavities, of which the following is a specification. My invention relates to a filling compound for tree cavlties, and more particularly to such'a compound as may be packedin'acavity or wound to'close the same.

One object of the invention is to provide means whereby the cavity or wound of a.

tree maybe so treated as to. prevent further decay after filling, such as by contraction,

or breaking away of. the filling. from the 1 wood ofthe. tree within the cavity,'thereby,

exposing the wound to the action. of the ele ments of the atmosphere and to water, such as rain.

In all of the compounds for the above purpose in use, as far as is known to me,

mlvide a filling of fluent material in the form contraction of the filling,'or breakingaway thereof from the wood within the cavity occurs, whereby the wound is exposed to the manufacture.

.Anotherobject of my invention isto pro- I of granules or small particles which may be slightly heated and tamped, or packed into the wound or cavity and preferably after first enlarging the cavity, cleaning and sterilizing the same, and applying to or paint-- ing the wood within the cavity with a suitable water-proofing agent in liquid state;

Another object of the invention is to provide thecompound referred to of such composition as to enable the use of asphalt or asphaltuni in its natural form or the o1l thereof. a Afurtherobject of the invention is to rovide a. filling which may be applied in am or',rainy weather and also cold wee er, the "latter being impossible where temperature.

The cavity is preferably--enlarged to..such an extent or shape as to prevent the filling therein from'falling therefrom should the filling sever or break from the wood within the cavity. Thereupon the wood within the cavity is preferably treated or painted with a suitable water-proofing compound whichmay be .in the form of a liquid, and for which purpose a compound, having pine tar,

resin and asphalt as the ingredients 'inproper proportions has been found efi'ective and satisfactory. After such treatment .of the wound, my filling is inserted or applied, whichfilling is prepared and, applied as follows: f

A suitable quantity.

oil, is mixed with a suitable filler, either organic or inorganic in nature, and such as saw-dust, Zsand, crushed. rock,. or' the like," which has been found suitable both as to effectiveness and low cost. may be mixed in any suitablepropdrtions deslred'. In use it has been found that seven parts of the filler to one part. of the asp? .lt

of asphalt or as- I phaltum, either in its natural form, or the' Said substances I or asphaltum produces an eflicient and satisfactory compound. In the preparation of the compound the filler is placed in the as phaltum while the latter is in a boiling state and the filler is preferably stirred or agitatedin the hot or boiling asph'altum to insure that the cementitious material will coat each particle of the filler. The mixture is then allowed to cool and when cool assumes a granular form, or is 111 amass of small particles and may be readily handled.

in applying the filler, it is preferably first slightly heated and in such state inserted or placed in the tree cavity or wound and then tamped or compressed into compact form to provide a solid (filling; uponsetting or The fil firmly adheres to-the wood withinthe cavity .In this state the filling is used for inser-, i

' tion in ,the cavity or wound of thetree. But

and being elastic, tend; to in itself firmly in position; thus obviatingany danger ofthe filling being severed from'the wood with:- in'the cavity and consequently the danger of contraction of the filling, permittingrain and the elements togain access to the wound-.

ed parts of the tree'within the cavity, re-

sultlng in further decay. This danger which is avoided by my invention, often occurs with the fillings now in' use and-before referred to andlwhich fillings comprise in their composition, prineipally, concrete-or cement. I 'Aslalso setforth, the composition is one which will harden or set rapidly regardless ofweather conditions and hence' is capable of application at all times. v

' Further, it will be evidentthat the com-' position thus formed is of such a nature that the inherently elastic qualities of the filler arenot-materially interfered with by the use of the binder as the binder is-not im pregnated through the filler, but at the same time the coating of the particles of filling material protects. the; same against the ab- 21 sorption of moisture or ageinstundue influence from external agencies; 3 The'preferred embodiment of the composition has been set forth and dribed here,-

, in, but it will be wide we .1 that the steps taken 'in the mixing of the edients may be varied and that even the, proportions could perhaps he changed; it however essential that a relatively lnrrquantaty .o filler-material than ofhinder be employed,

' i mariner at that other mitates might ma nta to within the spirit and scope of the invention and the appended claims.
